How loudspeakers / Beyma works?

Hinge membrane (often several waves) is actually to its flexible anchor. Lifetime suspension gives the most waves and membrane life itself. The material is used rubber and polyurethane, which can be found especially in Tonsil speakers. After the suspension is expected to be mainly thermal and temporal stability and optimal flexibility. The cone will meet with grafitovaným paper and polypropylene, which has the advantage that the frequency response of the speaker uses a polypropylene membrane to minimize the side elevation on the upper edge of the transmitted band. These speakers are especially suited for dual-band HIFI system. For high altitude and speakers find středovýškových membranes made of titanium and aluminum. The membrane must be sufficiently rigid and light that flickered Pístov the widest frequency band. Centering membrane holds the voice coil to the membrane in the air gap magnetic axis, which prevents friction parts of the coil magnetic circuit. Centering element must be lightweight and breathable. The quality of speakers Beyma meet up with two centering membranes. Shorting ring serves to reduce the influence of magnetic field modulation of magnetic voice coil. After connecting the terminal asks good solderability and heat resistance. The positive pole of the speaker is marked with a red circle.

Midrange speaker Whether or A direct pressure, you deserve when selecting at least as much attention to subwoofers. Remember that the speaker is working in the zone where the human ear is most sensitive, and therefore would be best. Be wary of speakers with a closed cage. These speakers, which is the volume of work created nevystřižením holes in steel cage, although usually cheaper, but not too good. The best course is when the speakers to try and listen to the reproduction of musical and sinusoidal signals. Propísknutí quality generator can detect any distortion and resonance.

The magnetic circuit is the head of the speaker. Used as a permanent magnet with a soft magnetic pole piece. The material is usually ferrite for high-end types will find a magnet with the addition of rare earth (Nd). The magnetic circuit is designed so that the magnetic field in the gap as far as possible balanced (less distortion). For better heat dissipation is cooling vent, which reduces the effect of thermal compression. The voice coil is wound is often copper wire, the windings are the best types of flat copper-coated aluminum wire, which contributes to improved job performance gap and thereby increase the effectiveness of the speaker. As kostřička voice coil (Former here) is the material of heat resistant polyamide? Kapton. If you decide to buy any speaker, first thoroughly consult catalogs of manufacturers – paid to buy a pig in a poke. Note also the different measurement conditions different manufacturers. After purchasing the speaker paid his crib all the parameters from the company catalog – just in case the later substitution. For your choice of speakers was easier, please see the illustration on the HiFi speaker kits, which have long been tested by our customers.

The section of speakers we have set aside traditional audio speakers for their own construction, repair and renovation speaker boxes. You will find the dome tweeter, drivers, subwoofers, woofers, loudspeakers, midrange speakers, bass speakers and horns, broken down by producers. Specific instructions, procedures, theory and drawings for the speaker box cabinet construction see in design – the theory section.
